PayNexa

PayNexa is a fintech payment platform built as .NET 10 microservices (Customer, Authentication, Payment, Transaction, Notification) behind a YARP API gateway. Each service follows Clean Architecture, DDD and CQRS. Writes go to SQL Server, reads come from MongoDB read models, and Redis is the cache. Events flow to Kafka through a transactional outbox. Every request is logged end to end with Serilog, Seq and OpenTelemetry under one correlation id, with personal data masked. The whole stack runs in Docker.

Personal Blog Website

A personal blog and project portfolio built with NestJS and TypeScript, deployed to an AWS EC2 instance by a Jenkins pipeline that runs on every push. Docker builds the image, the tests run inside that image, and a named volume keeps posts, projects and uploaded photos alive when the container is replaced. It includes a Markdown editor with drafts and scheduling, a searchable project portfolio, an About page with a photo gallery, and an image pipeline that resizes on demand and builds social preview cards.

backend blog

A backend REST API for a personal blogging platform, providing secure authentication, content management, and scalable APIs for creating, publishing, and managing blog posts.
